Wouldn't 'Let's go get smarter together' or 'today' or something of the likes be a bit more appropriate, due to it being an instance of becoming smarter rather than a culmination of instances at once? I feel like 'let's go get smarter every day' for one specific instance of becoming smarter is a bit misplaced and misnomed in comparison, and leads to a moment of awkwardness in my mind; as if it's advice, rather than a welcoming invitation. Maybe it's a solo perception, but here's to hoping this mention of insight can provide some benefit. Cheers, Destin.

They DO NOT send all of the hydrogen overboard. lol. What do you think they are cooking with in the galley and for emergency power? I don't understand why they keep trying to keep that a secret. They talked about it openly on season 2 of mail bag. OBVIOUSLY you arent going to waste a perfectly good source of compressed hydrogen and just dump all of it back in the ocean.

Your videos are so great, especially when you interact with people at their daily jobs like this. Your genuine interesting in learning and fascination with the technology catch a lot of them off guard, they may think it's boring or no big deal but once they are in the video and see how much other people want to know they get excited too. Thank you Destin, for your channel and your personality.

I was surprised when the guy said about the solidified ash left behind "they call them clinkers, I don't know why" it's because sometimes when conditions are right in a wood stove some of the ash almost glassifies and the chunks clink in the bucket when you clean out the ash. Really cool, I've heard about oxygen candles but never saw one in action.

We do not breath oxygen but air , 78% nitrogen , 21% oxygen , 1% other gases. Medical oxygen, 99% oxygen, is however considered as a drug or pharmaceutical product .

In the construction world it is a common thing for most people to say driving on frost causes it to freeze deeper into the ground. Would love to know if driving on it is the direct cause or if compaction of soil lowering the r value is the cause for it to go deeper?

Think of the pre heater for the MEA as a progressive heater that allows the mixture to come up to temp faster.
CandynoseTwinskins Timme sedan
So many uses for 9 inch nails haha
Fullgrizzly94 Timme sedan
If I had to guess, the pre-heater before the MEA boiler is to heat the MEA faster so less energy can be used in the boiler section, which might also save time. Because the liquid is moving through the heated pipe section, they can make use of convection and not have to wait on the convection flow within the tank.

It's called a clinker because The word was passed on from UK submariners - original clinker bricks are bricks of clay made kinda shiny brittle and/or vitrified during a firing that exposes the brick to very excessive heat. Real/actual building clinkers are/were commonly used in the UK for building homes, to add historic looking appeal. People still use them to build homes that they want that certain aesthetic - it (more) often does from people using reclaimed clinkers now, as they aren't made very often anymore..... Phew, that's probably a bit too much info. But there you go, in short: a clinker is just a brick exposed to very very high heat.

So why don't they use a couple plants and shine some light on them? They tried it in a russian closed atmospherics experiment and the problem was the plants grew and quickly produced too much O2, causing a fire hazard, so they had to start burning plants to remove some of the excess O2. But with some good controls and experienced operators it should be perfectly feasible.

i noticed you seemed a bit confused as to why the mea system used a preheater. I am fairly certain it has to do with gas retention. Hotter liquids retain less gasses than cooler ones.

Dow is from Southern Ohio. That part of the world seems to have very little annunciation. I work in that area quite a bit and it takes a good deal of time to pick out the dialect. I hear what he is saying as words but cannot discern where one word starts and ends. Dustin says "say it slower"..."no slower" and you still cannot pick it wicked smaaaart kid though

I bet you those are called clinkers because they are similar to the clinkers blacksmiths make when burning coke or coal as fuel in a forge. They look so much like giant cylindrical versions of the clinkers that come from forges.

I think the "preheating function" is just a heat exchanger with the output of the boiler stripper. Take the energy out of the lean MEA to better condense it and put in the rich MEA that you're about to boil. Save some time, save some energy loss.

I got a good chuckle when he said the oxygen generator was "down." I spent 3 years on a boat and not once did we ever operate that piece of equipment. It's nickname was "the bomb" due to the fact that it generates hydrogen gas and can be extremely dangerous. When we went on mission and would stay underwater most of the time, we'd just load up on oxygen candles and burn them as necessary. It was not uncommon for oxygen to drop to around 17%, which makes you constantly tired no matter how much sleep you've gotten. The other thing is that clean, potable water is at a premium on a submarine. Our distiller could provide 10k gallons per day (if the operator knows what they're doing, if they weren't very proficient then significantly less). That's for the entire boat: drinking, washing dishes, laundry, showers, etc. We'd have to constantly remind people to limit their water use so that we didn't run out. It would make little sense to waste water on making oxygen when you can just burn a candle. Oh, and amine? It gets everywhere. Go up to any AC vent in the engineroom and you'll notice a slight drip of an oily substance. That's amine. It will funk your clothes up for weeks after, even with repeated washing.

The MEA being processed is similar to a LiBr absorption chiller that uses steam or hot water to boil the H2O (which is the refrigerant) out of the bromide solution and repeats the cycle. This chiller also runs in a vacuum.

He said two at a time maximizes O2 output.. obviously that's true per minute, but did he mean overall output? Does the Oxygen in the candle bond with another molecule creating a waste bi-produce or the like which is reduced when another nearby candle is also consuming the incidental molecule?

When I was a young kid, I took my Snapciruits kit and put each end into a cup of saltwater in an attempt to produce hydrogen. Thankfully, I didn't poison myself, but one of the ends of the extenders turned bright green, like the Statue of Liberty, and the other turned bright orange, like unoxidized copper.
